Make WikipediaDatasetCreatorMapper fuzzy category match respect word boundaries
-------------------------------------------------------------------------------
Key: MAHOUT-271
URL: https://issues.apache.org/jira/browse/MAHOUT-271
Project: Mahout
Issue Type: Improvement
Components: Classification
Affects Versions: 0.2
Reporter: Olivier Grisel
Assignee: Olivier Grisel
Priority: Trivial
Fix For: 0.3
WikipediaDatasetCreatorDriver is useful to create categorisation corpora out of
wikipedia, however the category match just do a String#contains check which can
catch a lot of unrelated categories.
Checking the word boundaries with a regexp such as String.format("\\b%s\\b",
theCategoryNameIAmLookingFor); should fix the issue.
